Patented June 16, 1931 UNITED STATES JOHN E. EBICKSON, OF EAST GRAN-IDFORKS; MINNESOTA FUNNEL Y Application filed April s, 1929. Seria1.No.3.56,561. r r p with the filling neck 18 for the tank to This inventionrelates to filling'devices for tanks, barrels and other forms ofreceptacles for storing liquid.

An object of the invention contemplates 5 the provision and arrangementof means upon the funnel whereby liquid above a predetermined level willbe diverted ofi to pre-' vent spilling of the liquid upon theoverflowing of the receptacle.

An additional object of the invention consists of a closure and supportfor the funnel to prevent air from escaping under displacement.

With the above and other objects in view, the invention further consistsof the following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claim.

In the drawings V Figure 1 is an elevation of my invention as appliedand in use.

Figure 2 is a horizontal sectional view taken through a receptacle, theoverflow device and container for catching the overflow.

Referring to the drawings in detail wherein like characters of referencedenote corresponding parts, the reference-character 10 indicatesgenerally a tank or other storage receptacle employed as a reservoir,the contents of which is to be carried off bya pipe line .or faucet, notshown, preferably located adjacent the bottom wall therefor. ventioncontemplates the arrangement and provision of a funnel 11 having apacking or gasket 12, preferably composed of rubber or analogousmaterial and of frusto-conical shape being arranged within the fillingneck 13 for the tank.

The gasket or packing is centrally apertured to facilitate projection ofthe spout end 14 of the funnel therethrough in order that a positiveseal will be established therebetween. The upper or base end of thesubstantially inverted frusto-conically shaped gasket or packing isengageable with the under side of a closure cap 15' carried upon theouter portion of the funnel neck immediately below the connection of themouth therefor. 59 The closure cap 15 is threadedly engaged Theincompress the gasket or packing 12 whereby 'tlieentire filling neckwillbe sealed.

[An overflow lpipe, designated as at 16, is shaped to dispose a portionthereof through theside wall of the mouth of the funnelwhereby theadjacent portion of'its length may be curvedu'pon itself'and centrallydisposed within the neck ltf Anoflsea-for'med adjacent the innermostprojecting end of the overflow pipe, is in turn passed through anopening in the side wall of the neck 1 1 immediately above the lowerextremity thereof.

The outermost end of the overflow pipe is projected downwardly outsideofthe funnel and tank 10 for final disposition within the mouth of adrip pan or overflow receptacle 17.

As generally known-in the filling of containers with. liquid that equalamounts of air 'must be displaced and such escape action generally,takes place about and within the filling neck of the receptacle. In thepresent invention, the filling neck is sealed by the attachment of thefilling device therewith save for the bores of the funnel spout andoverflow pipe for the receptacle. During the fillingof the tank 10, withthe present invention employed, the head of liquid passing through thespout 14 for the funnel will restrict the escape of air therethroughwhere by the air will be caused tofind its way out of the tankthroughthe bore of the overflow pipe 16. e

When the liquid level in the tank 10 reaches a predetermined height,governed by the projection of the overflow pipe 16 therein, the airunder compression by liquid displacement will force a head of liquid upwardly and through the overflow pipe 16 until the liquid levelcompletely covers the lowermost offset end of the overflow pipe. Thepresence of the overflow liquid in the drip pan or overflow container 17will signify that the tank 10 has been filled to a certain ture of theliquid is dangerous and obnoxious;

The invention is susceptible of various changes in its form, proportionsand minor v vdetails of construction, andthe right is herein reserved tomake such changes as proper- 5 1y fall Within the scope of the appendedclaim.

Having thus described the invention, what is claimed is An overfillingoverflow device comprising a filling element having an enlarged entranceend, a tubular discharge portion for the filling element being ofcorresponding width throughout its length, a discharge tube projectedthrough the enlarged entrance end of the filling neck anddepending'centrally of the longitudinal axis of the tubular dischargeportion and having a bore equivalent to that of the latter, said tubehaving the innermost end thereof projected through the Wall'of thetubular discharge portion and at right angles to the bore thereof, andthe outermost end of the discharge tube being disposed outwardly andbeyond the entrance end of the device, In testimony whereof I afl'ix mysignature.
